I've been researching LL-37 for 3 months now due to past lab results coming back showing contaminants! Now more recent lab results show contaminants are gone. The only thing i changed was incorporating LL-37 to my lab routine!!! I will now cycle the lab off for 30 days and start again at the lab for 2 months after that! GREAT pep!
